Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
formatSecondsToTime(int timeInSecond, int timeStartInSeconds) → String
It takes in two integers and returns a string.
getCurrentTimeInSeconds() → int
getCurrentTimeInSeconds() returns the current time in seconds
getCurrentTimeInSecondsFormatted() → String
It returns the current time in seconds formatted.
maybeUpdateTimeStart(covariant CountDownTime oldWidget) → void
If the timeStartInSeconds value has changed, reset the timer
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
resetTimer() → void
setCurrentTimeInSeconds(int value) → void
If the value is greater than or equal to 0, set the currentTimerSeconds to the value, otherwise set it to 0
setIsUnmounted(bool unmounted) → void
Set if the widget is unmounted
setTimeStartInSeconds(int value) → void
It sets the timeStartInSeconds variable to the value passed in.
startTimer(int timerDefaultValue, [dynamic timeCallback(int)?]) → void
StartTimer takes an int and an optional function that takes an int and returns nothing, and returns nothing.
stopTimer() → void
If the timer instance is not null, cancel it
toString() → String
A string representation of this object.
